Elvin bashed Baker in a DB BFT, Baker took offense in public & called Elvin out, which resulted in a drum battle in, I think, London. Everybody kissed & made up after the concert and lived happily ever after.

The remix itself is the Sex Machine - Readymade Jazz Defector Remix from the recently released Dynamite X compilation, which itself is a somewhat partial reissue of the Japan-only James Brown Ultimate Remixes collection of 2002. The Dynamite X thing is being trumpeted as a "new" issue, but it's "new" only in that it drops three remixes from the original album and adds two new ones.
